POLYESTERIMIDE COMPOSITE MATERIAL Russian patent published in 2020 - IPC C08L79/08 C08K7/14 C08K7/04 C08G73/16 B29C64/10 

FIELD: chemistry.

SUBSTANCE: invention relates to composite materials intended for additive production technologies. Disclosed is a polyesterimide composite material consisting of, wt%: polyetherimide as thermoplastic polymer (50–60), glass fiber or carbon as filler (30) and plasticizing additive (plasticizer) – polyphenylene sulfone oligomer based on 4,4'-dihydroxydiphenyl and 4,4'-dichlorodiphenylsulphone with molecular weight of about 15,000 g/mol and characteristic viscosity of 0.1 dl/g (10–20).

EFFECT: disclosed composite material has improved plasticity and fluidity of the melt, which improves cohesion of polymer threads in the sample when used in additive techniques.
